KIMI Piano 声音之旅

Create KIMI Piano: A Journey of Sound, an interactive 3D educational experience inspired by the construction of a Yamaha CFX concert grand piano. Use a warm off-white background, restrained museum-style typography, an orthographic camera, soft studio lighting, and delicate contact shadows. Show a black lacquer grand piano with ivory and black keys, a golden cast plate, steel and copper strings, spruce wood, felt action parts, brass hinges, pedals, legs, and casters.

Build a detailed assembly that can transition from the complete piano through a layered exploded view into a carefully arranged overhead flat lay. Use the Yamaha CFX exploded reference photograph to guide the shapes and arrangement of the 823 visible contour units. Preserve holes, curved outlines, bent case walls, and recognizable small hardware. Treat these as visible reference units rather than a verified count of physical piano parts. Keep unidentified pieces explicitly unconfirmed and avoid inventing their mechanical roles. Include an 88-key keyboard and a clearly illustrative string layout, without presenting the demonstration's string count as a factory specification.

Provide two connected experiences. The guided Journey of Sound should have eight chapters tracing how the keyboard, action, dampers, strings, bridges, soundboard, and supporting structure contribute to sound, ending in the complete flat lay. Use a clean cutaway with filled section surfaces to reveal the mechanism, then smoothly separate and emphasize the relevant assemblies. Keep fine strings, rods, and action parts readable while surrounding surfaces fade. Coordinate camera movement, explanatory text, and component motion, with space reserved for the text beside the model. 把三角钢琴替换为小提琴：章节改为琴身、音柱、低音梁、琴弦与琴弓如何协同发声，保留八章导览与自由拆解双模式，配色改为暖木色工作室背景。 The free-exploration view should offer assembled, flat-lay, outlines, reference photo, photo overlay, and 3D orbit modes. Include an assembly-progress slider, play-disassembly and reassemble controls, an exploded-view shortcut, reset, zoom, and pan. Add a searchable parts catalog with system filters. Hovering highlights a part; selecting it opens a focused view with its name, description, system, and reference information.

In the guided experience, provide chapter navigation, a continuous chapter slider, previous and next controls, play, pause, replay, English and Chinese text, and a link to free exploration. Keep transitions reversible and continuous, with no clipping, overlapping parts in the final layout, or components hidden behind the interface. Respect reduced-motion preferences.
